Kinda apropo to nothing, when SPICA debuted with "Russian Roulette" there were a couple fancams that started to go viral (of course this was pre-Crayon Pop's "Dancing Queen" promo, so fancams were still a niche thing) as the song was good and so were the visuals...
a couple surviving examples
But their distributor at the time (pretty sure it was Warner) DMCA'd them. (And, well, Spica remains a niche thing. )
